Status Displays 19-25Point-to-point frame relay IP connections will display a Netmask of255.255.255.255, which is the default Destination Mask value for HostIP routes. The Network Mask/NetMask configured on the IP interfaceis used by RIP for route summarization.Each entry is two lines on the screen, with the Netmask on the second line,under the associated Destination.ARP TableTo display a list of active ARP (Address Resolution Protocol) table entries, press [B]at the IP Status Displays Menu (or [C], [F], [G], [B] from the Main Menu).Information in this Display:l IP Address – Address of corresponding IP Interface.l MAC Address – MAC address to which each IP address maps.l AgeOut Timer – Time (in minutes) until the address will be removed from thetable if no traffic is received from that address. The address is added to the tableafter the FRM sends an ARP request for an IP address and receives a MACaddress in response. The timer is reset if an IP frame is received from the eitherthe IP or MAC address.If the screen is filled with information, you will be asked whether you want to displaymore.The ARP table does not include entries for devices that have no LAN inter-faces.IP InterfacesTo display a list of active IP interfaces, press [C] at the IP Status Displays Menu (or[C], [F], [G], [C] from the Main Menu).Information in this Display:l Name – identifier used in the IP Route Display. Each name is the interfacenumber preceded by the interface type, which is one of these:fr Frame relay x X.25 en Ethernettr Token Ring lo LoopbackThe loopback interface is added by the FRM, and has anumber one greater than the highest configurable interfacenumber (to avoid a conflict)..l MTU – Maximum Transmission Unit, the maximum size (in bytes) of the datafield that can be used to encapsulate an IP datagram for transmission over theinterface.l Network – bit-wise AND of the IP Address and the Mask.l IP Address – IP address of the local interface.l Rem Address – IP address of the remote device.
